Three Sesquiterpenoid Dimers from Chloranthus japonicus: Absolute Configuration of Chlorahololide A and Related Compounds.
A novel sesquiterpenoid dimer, named multistalide C (1), together with two known congeners, shizukaols C (2) and D (3), was isolated from the whole plant of Chloranthus japonicus Sieb. The structures of compounds 1-3 were elucidated by extensive HR-ESI-MS, 1D, and 2D NMR spectroscopic analysis. Compounds 1-3 exhibited significant toxic effects on brine shrimp larvae (Artemia salina). The absolu...
متن کاملChemical composition and antimicrobial activity of the essential oils from Chloranthus japonicus Sieb. and Chloranthus multistachys Pei.
We examined the composition and antimicrobial activity of two essential oils from Chloranthus japonicus Sieb. and Chloranthus multistachys Pei. GC-FID and GC-MS analyses identified 48 and 39 compounds, which represented 95.56% and 94.58%, respectively, of all components in these oils. Of these, 28 compounds were common to both, with a relatively high amount of oxygenated monoterpenes (50.95% an...
متن کاملNew sesquiterpenoid from the mushroom Sparassis crispa.
A new sesquiterpenoid (1) was isolated from the mushroom, Sparassis crispa, along with a known sesquiterpenoid (2). The structure of 1 was determined as (3R(*), 3aS(*), 4S(*), 8aR(*))-3-(1'-hydroxy-1'-methylethyl)-5,8a-dimethyldecahydroazulen-4-ol by the combination of NMR and ESI-MS analyses.
متن کاملUgandenial A, a new drimane-type sesquiterpenoid from Warburgia ugandensis.
One new drimane-type sesquiterpenoid, named ugandenial A (1), was isolated from the ethyl acetate extract of the bark of Warburgia ugandensis (Canellaceae) together with eight known drimane-type sesquiterpenoids: 11alpha-hydroxycinnamosmolide (2), warburganal (3), polygodial (4), mukaadial (5), dendocarbin A (6), 9alpha-hydroxycinnamolide (7), dendocarbin L (8) and dendocarbin M (9). Their stru...
متن کاملA new sesquiterpenoid hydroquinone from the marine sponge Dysidea arenaria.
Detailed chemical investigation of the South China sponge Dysidea arenaria resulted in the isolation of a new sesquiterpenoid hydroquinone, 19-hydroxypolyfibrospongol B (1), along with five known compounds: polyfibrospongol B (2), isosemnonorthoquinone (3), ilimaquinone (4), smenospongine (5) and smenotronic acid (6). The structures were determined by extensive spectroscopic analysis. The in vi...
